About

Mammillaria bombycina, the silken pincushion cactus, is a species of flowering plant in the family Cactaceae.

How to grow it

Mammillaria bombycina is one of many Mamillaria species to be cultivated and is among the easiest. In temperate regions it must be grown under glass with heat, preferably in full sun. It has gained the Royal Horticultural Society's Award of Garden Merit. The plant can be grown from seeds which are collected from the ripe fruits.

Where it grows

It is native to Jalisco and Aguascalientes states, in western central Mexico at altitudes between 2340 and 2500 meters. Because of illegal collecting, the wild population is considered to have a vulnerable status.
